The forward extremity ofthe tubular casing 10 is provided-with a screwtl1readed section 12 for engagement with an annular member 13`for supporting an outf wardly extending flange member 14 on a' ref iiector 15.

The opening 15 in the reflectorl has a diameter lsuch that the lamp receiving socket 17 may pass freely therethrough without contact with the re'A `flector in order to provide for focusingadjustment of the lamp 19 along the axis of the re1ector15.` v lAt a point spaced to ythe yrear ofthe reflector 15 is Va septum or partition 20ormed 'of insulating material and seatedat its edges in a' groove 21 formed inthe inner walloi' vthe casing member 10Q The septum ormfr'am'e vmember 2O provides a support forthe lamp supporting devices as well as Vfor switch mechanism andv focusing devices" hereinafter referred to. rlrheseptum 2O is heldin place fin the seating groove 21 by means of a pair oi strut members 22v attached yat their lower ends v,to the septum 2O and provided with shoulders 23 near their upper ends which are adapted i;

toengage beneath a pairof inturned lugs or Hange members24 formed on the edge of the l casing 1Q. In order.. to Aremove. the frame member'20 and the parts' supported .thereby "v freely removed through the open end ofthe casing 10.

* 1 .The lamp receiving socket 17,is.suppor ted vby a bracket member 26 which isin yturn slid# L ablymounted ina guideway 27 carried by the frame member 20. The bracket member 26 is jects Aoutwardlyfthroughthe side wallet the casing 10 inapositionaccessible tothe thumb `ofthe user. The thumbmember28 is movable in ia slot 29gifn the casing 10 and operates Y.

through slits vf-crmed for the purposein thev lguide member27. By this arrangement and construction, movement of the thumb piece 28 longitudinally oi the'casing 10 provides ics for the `corresponding adjustment of the'lamp 19'carried by -thebracket 26 along the axis of the reilecting member 15.

'Y K'In order to rvcontrol the operation the lamp 19 'l by ymaking or 'breaking' a circuit therethrough, a spring contact member 30 is mounted on the frame member 20 and engages the downwardly,projecting contact 31. formed on the inner end of the lamp plug 18, the spring contact 30 operating to maintain engagement with the contact 31 in all the adjusted positions into which the lamp 19 may be placed. A downward extension 32 of the spring contact member 30 occupies a position' such th at a switch member pivotally mounted at 34 on a bracket 35 can be moved into engagement with the spring contact 32 when an actuating button or handle 36 is moved from the full-line to the dotted-line position shown in Figure 1 ofthe drawings. The bracket member 235 on which the switch member 33 is mounted, iscarried Aby the frame member 2O and is at all times in contacting engagement with the center contact 37 of the battery cell 11 so that engagement of the switch member with the contact 32 completes a circuit through the lamp 19 as follows: outer pole of battery cell 11, slidway Y27, bracket 26, socket 1'?, lamp contact 18, filament 38,lampl contact 3l, spring contact 30, spring contact 32, lswitch member 33 and bracket member 35 to contact 37 of battery cell 11. It is usual, in electric han-d lamps of this class, to establish electric connection between the Zinc cup of the dry cell and the casing of the hand lamp, the casing thus serving as a portion of the circuit.` In the present instance, the circuit is completed from the casing tothe member 26, as illustrated in Fig. 5. I

In order' to hold the switch member 33 in either its circuit closing or circuit opening position, a spring member 39 is provided VVwhich engages with flat surfaces l() and 41 formed on theedge of the switch member 33 to hold the switch member in either one of its operative positions.v y f In order to facilitate the operation of the switch member 83 and the focusing bracket 26 by the thumb of the .same hand of the user, the operating member 28 of thel focusing devicer and the operating member 36 of the switch levice are placed in closeproximity to each other-as is indicated in Figure 2 of the'drawing. eration of both the switching device and the focusing device can be achieve-d without-the use of both hands of the operator, thereby leaving the other hand free and completely controlling the lamp by the hand Vin which it is held.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my e invention could be made without departing from the scope thereof, it is intended that all matter contained in the above-description or shown in the accompanying drawings shall' be interpreted as illustrative and not in a limiting sense.

By this arrangement the op- It isl also to be kunderstood that the `language used in the following claims is in-A tended to .cover all the generic and specific features of the invention hereiny described and all statementsof the scope of the invention which, as a matter of language, might be said to fall therebetween.
